Summary: This lesson aims to help students with quadratic functions y = ax2 + bx + c. This is the next step after linear functions bx + c. The lesson begins with three quadratics and their graphs (three parabolas): y = x2 - 2x + (0 or 1 or 2). The prerequisite or co-requisite for this lesson is some working experience with algebra, like factoring x2 -2x into x(x-2).]]>

Summary: The objective of this lesson is to get students acquainted with the basic principles of sea water desalination and to make them appreciate the importance of sea water desalination in the Kingdom of Saudi Arabia due to the scarcity of fresh water natural resources. This requires a discussion of osmosis and reverse osmosis as the fundamental physical properties upon which sea water desalination works.

]]>**In this module, the idea is to put students in a similar situation as the one faced by astronomers when mapping the universe. They need to look for the means to make measurements without what we consider the intuitive way of doing so. The idea is to show them also that the technique used is not fancy or complex, but based on simple and easily applicable and understandable concepts.**

Summary: Exponential growth is keenly applicable to a variety of different fields ranging from cell growth in biology, nuclear chain reactions in physics to computational complexity in computer science. In this lesson, through various examples and activities, we have tried to compare exponential growth to polynomial growth and to develop an insight about how quickly the number can grow or decay in exponentials.]]>

the adaptations of that system over time have made it different than that of other living creatures,

especially mammals. Birds are omnipresent in our lives, and students will come to understand and

appreciate the fascinating inner workings of these beautiful creatures.]]>

Summary: Beavers are generally known as the engineers of the animal world. In fact the beaver is MIT's mascot! But honeybees might be better engineers than beavers! And in this lesson involving geometry in interesting ways, you'll see why! Honeybees, over time, have optimized the design of their beehives. Mathematicians can do no better.]]>
